DEEP WATER CONSTRUCTION
Coastal Marine Construction executes deep water construction using our own barges, tugboats, and cranes, supported by in-house diving and underwater welding capability.
This lets us take on marine scope that many contractors have to subcontract out.

PLANNED
AROUND THE WATER.
Deep water projects raise the difficulty on nearly every part of a marine job, from equipment access to diver safety to the logistics of moving materials offshore. Coastal Marine Construction owns the marine equipment fleet needed to work in these conditions, including barges, tugboats, and cranes, rather than renting or subcontracting access. Our diving services include underwater welding and underwater blasting, which allows structural and repair work to happen below the surface without waiting on a separate specialty sub to mobilize.
Our process starts with a site and engineering review to understand water depth, current conditions, and access logistics before equipment is mobilized. Marine transport brings materials and equipment to the work site, and our diving crews handle inspection, welding, or repair work below the surface while surface crews manage crane and barge operations. We maintain close coordination with project engineers throughout, since deep water conditions can require real-time adjustments that a subcontracted diving crew without full project context would struggle to make.
CLIENT TESTIMONIALS
FREQUENTLY ASKED QUESTIONS
What is considered deep water construction?
Deep water construction refers to marine construction work performed in water depths that require specialized equipment, diving support, and offshore logistics beyond standard nearshore construction methods.
Does deep water construction require diving services?
Often, yes. Deep water projects frequently require underwater inspection, welding, or repair work, which Coastal Marine Construction performs with in-house diving crews rather than subcontracting.
What equipment is needed for deep water marine construction?
Deep water construction typically requires barges, tugboats, cranes, and marine transport capability. Coastal Marine Construction owns this equipment fleet rather than relying on rented or subcontracted equipment.
Can Coastal Marine Construction perform underwater welding?
Yes. Underwater welding is part of Coastal Marine Construction’s in-house diving services, allowing structural repair and construction work to happen below the surface.
What types of projects require deep water construction capability?
Offshore infrastructure, port and terminal projects, wind energy support facilities, and large-scale wharf or bridge projects with deep channel access often require deep water construction capability.
How does Coastal Marine Construction manage safety on deep water projects?
Coastal Marine Construction applies company-wide safety protocols that conform to OSHA standards across all diving, crane, and marine transport operations, regardless of water depth.
